Job is so useless, you either get STD or nothing in return except for that good old virtual slurpy slurp.
I wanna suggest so that it atleast heals you, and much faster than a Medic can when you successfully did it with a prostitute. I see this balance perfect cause once again, it comes with the risk of contracting STD which will give you nothing but a painful slow death, or wait till you're done with the prostitute which takes about 15 seconds for the proposed healing feature I mentioned, whereas a Medic is much safer and can do it immediately without any risks after offering their services, only with a slower rate of healing.
I was also thinking about prostitutes having the ability to heal you up to 125 HP, it does sound nice on paper but I feel like this will be complicated.
